The diversity and ecology of spiders were studied in Ngoc Thanh buffer zone of Tam Dao National Park, Cuc Phuong buffer zone of Cuc Phuong National Park, and Ba Trai buffer zone of Ba Vi National Park. Spiders were collected by five methods: pitfall traps, litter sampling, tree beating, sweep netting and visual searches in four types of habitats in...

A new genus and thirteen species of jumping spiders from northern Vietnam are reported. Zabka gen. nov. is erected to accommodate two species transferred from Euophrys Blackwall,1841, including the generotype, Z. cooki (Żabka, 1985), comb. nov., and Z. xuyei (Lin & Li, 2020), comb. nov. Twelve new species are described: Chinattus crewsae sp. nov. (...

A faunistic inventory is proposed for the known Vietnamese scorpion species. The aim of this contribution is to bring an up-to-date checklist of all known species in Vietnam, prior to a more detailed study of the Vietnamese fauna to be performed by one of the authors (T.-H.T.) in the context of the preparation of a doctoral degree. Final taxonomic...
Article
Status survey of the cave scorpion, Euscorpiops cavernicola, was carried in a cave system of Bac Kan province. A total of 56 (9 adults) and 45 (7 adults) individuals were recorded during the years 2014 and 2015, respectively. This species is only known from Hua Ma cave, which is strongly threatened by tourism development. Based on the current area...

Living fossils are lineages that have retained plesiomorphic traits through long time periods. It is expected that such lineages have both originated and diversified long ago. Such expectations have recently been challenged in some textbook examples of living fossils, notably in extant cycads and coelacanths. Using a phylogenetic approach, we teste...

Among the genera of the subfamily Scorpiopinae Kraepelin, 1905 Alloscorpiops remains rather discrete. Only recently new species were added to this genus, increasing its number from two to five. Therefore, species of Alloscorpiops remain rare. One remarkable new species, Alloscorpiops troglodytes sp. n., is described on the basis of a single male sp...
Article
Scorpiops (Vietscorpiops) dentidactylus subgen. n. et sp. n., belonging to the family Euscorpiidae Laurie, 1896, is described on the basis of single male collected in Dien Bien Province, Muong Nhe District, Nam Vi Commune, in a limestone formation covered by rainforest, in the extreme North of Vietnam. The new subgenus is characterized by the prese...

One new species Belisana denticulata sp. n. (♂) is reported from northern Vietnam based on material collected by fogging the forest canopy. This species resembles Belisana scharffi Huber, 2005, but can be distinguished by relatively long distance between proximal parts of proximo-lateral apophysis and distal apophysis on male chelicerae, by presenc...
Article
Five genera and 26 species belonging to two subfamilies Arteminae Simon, 1893 (one genus and one species) and Pholcinae C.L. Koch, 1850 (four genera and 25 species) are reported from northern Vietnam, including 19 new species of three genera: Belisana babensis sp. nov. (male, female; Bac Kan), B. cheni sp. nov. (male, female; Bac Kan), B. clavata s...

In an era of biodiversity crisis, arthropods have great potential to inform conservation assessment and test hypotheses about community assembly. This is because their relatively narrow geographic distributions and high diversity offer high-resolution data on landscape-scale patterns of biodiversity. However, a major impediment to the more widespre...
Article
Euscorpiops dakrong sp. n., appartenant à la famille des Euscorpiidae Laurie, est décrit à partir d’un mâle et d’une femelle collectés dans une grotte de la « Dakrong Nature Reserve », située dans le district de Dakrong et dans la province de Quang Tri, au Vietnam. La nouvelle espèce présente les caractéristiques propres aux scorpions du genre Eusc...
Article
Une nouvelle espèce appartenant au genre Chaerilus Simon, 1877 est décrite d’une grotte située dans le district de Dien Bien, à l’ouest de Dien Bien Phu City, au nord du Vietnam. La nouvelle espèce est morphologiquement similaire à d’autres espèces de Chaerilus distribuées uniquement dans le Sud du Vietnam et du Cambodge. Ceci suggère un cas d’espè...
Article
Euscorpiops cavernicola sp. n., belonging to the family Euscorpiidae Laurie, is described on the basis of two male and two female specimens collected in the Hua Ma cave located in the Quang Khe commune, Ba Be district of Bac Kan province in Viet Nam. The new species presents most features exhibited by scorpions within the genus Euscorpiops, however...

Spiders were sampled from one-hectare tropical rainforest plots in three parks in northern Vietnam. Inventories were based on ecologically structured sampling employing five methods. A series of non-parametric estimators were used to extrapolate the true species richness from the samples for each locality and indicate the magnitude of sampling effo...
